To compile Lua SPOT, go to the Lua SPOT project directory and make the application suite by entering ant suite command as follows:
$ cd src/LuaSpot
$ ant suite
After executing that, under the suite directory, you can find a file called LuaSpot_1.0.0.jar.
To install the application to the Sun SPOT, run ant deploy in the project directory. This will compile and install the suite to the Sun SPOT.:
$ ant deploy
After the deployment, the Lua SPOT is ready to be used. Reset the Sun SPOT and after some time, you can see the LEDs turn to red. It tells that the Lua SPOT is initializing. If the LEDs turn to green and off after that, it means that the Lua SPOT in the Sun SPOT is ready to be used.
